Vent Requirements; Adding Restriction - Jøtul GF 400 DV IPI Sebago Installation And Operation Instructions Manual

139548-N GF 400 DV IPI 7/21
Venting Requirements
The Jøtul GF 400 DV IPI gas stove requires 4" x 6 5/8" co-
axial, direct vent pipe components and may be installed
with a vertical or horizontal termination. Vent installation
must conform to the configuration requirements
described herein.
This appliance is approved for use with vent systems
from the following manufacturers:
• M&G DuraVent, Inc. (Direct Vent Pro Series)
• American Metal Products (Amerivent)
• Security Chimneys International, Ltd. (Secure Vent)
• Selkirk Metalbestos (Direct Temp)
• Metal-Fab, Inc. (Sure-Seal Direct Vent)
• Industrial Chimney Corp. (ExcelDirect)
• Bernard Dalsin Manufacturing ( Pro Form )
• Olympia Chimney Supply, Inc. (Ventis Direct Vent)
Use parts of one manufacturer only - DO NOT MIX
VENT COMPONENTS FROM DIFFERENT MANUFACTURERS
IN THE SAME SYSTEM.
Installation of any components not manufactured
or approved by Jøtul or failure to meet all clearance
requirements will void all warranties and could result in
property damage, bodily injury, or serious fire.
The approved vent configurations described
in this manual are derived from extensive testing
under controlled laboratory conditions. Gas appliance
performance can be negatively affected by variables
present in the installation environment, i.e: atmospheric
pressure, strong prevailing winds, adjacent structures and
trees, snow accumulation, etc. These conditions should be
taken into consideration by the installer and stove owner
when planning the vent system design.
IMPORTANT
• JOINT SEALING
REQUIREMENT: APPLY
A 1/8" BEAD OF HIGH-
TEMPERATURE SEALANT
OR MIL-PAC® TO THE MALE
SECTION OF THE INNER VENT
PIPE. THE CEMENT SHOULD
FORM A SEAL BETWEEN THE
INNER AND OUTER PIPES. DO
NOT USE SILICONE SEALANT.
• NEVER MODIFY ANY
VENTING COMPONENT,
OR USE ANY DAMAGED
VENTING PRODUCT.
• THE GAS APPLIANCE AND VENT SYSTEM MUST BE
VENTED DIRECTLY TO THE OUTSIDE OF THE BUILDING
AND NEVER ATTACHED TO A CHIMNEY SERVING A
SOLID FUEL OR GAS BURNING APPLIANCE. EACH
DIRECT VENT GAS APPLIANCE MUST HAVE ITS OWN
SEPARATE VENT SYSTEM. COMMON VENT SYSTEMS ARE
PROHIBITED.

• IF VENTING SYSTEM IS DISASSEMBLED FOR ANY
REASON, REINSTALL PER THE INSTRUCTIONS PROVIDED
FOR THE INITIAL INSTALLATION.
Vent Restriction
The GF 400 DV IPI is equipped with an Exhaust Restrictor
Plate which enables regulation of exhaust gas flow.
The plate prevents overly strong draft that can cause
poor combustion and weak flame picture. Follow
the guidelines below, and on the following pages, to
determine the correct restrictor plate setting for your
particular installation configuration.
Exhaust Restrictor
The Exhaust Restrictor is an adjustable valve located
within the vent outlet. It is set in the FULLY OPEN position
at the factory. See Fig. 8. The five positions correlate to the
termination zones (A,B,C,D, E) diagramed in figure 9. Use
the diagram to determine the setting you should use.
Adjusting Exhaust Restrictor Plate:
1. Lift the Top Plate from the stove.
2. Loosen the locking screw and adjust the pivot plate to
the appropriate restriction setting that correlates to
the vent configuration.
3. Tighten the lock nut and replace the Top Plate.
NOTE:
Over-restriction of the appliance may cause cold-
start problems. The flame picture may appear weak
(ghosting) or the pilot may extinguish. Should this
condition occur, reduce restriction slightly until the unit
functions properly from a cold start. If more restriction
is desired, it may be necessary to operate the unit in
CPI ( continuous pilot ) mode in order to maintain
adequate flue draft.
Approved Horizontal
and Vertical Vent Terminations
See Fig. 9, Vent Termination Matrix
• ALL VENTING MUST TERMINATE (END) WITHIN ONE OF
THE SHADED AREAS.
• SET STOVE EXHAUST RESTRICTOR TO THE POSITION THAT
CORRESPONDS TO THE VENT TERMINATION AREA IN
THE MATRIX. When termination is exactly on a division
line, use the less restrictive position. For example, if
termination is at 18 ft. / 8 ft., restriction should be set at
Position C.
• Up to four 45° or two 90° elbows are permitted in
addition to the starter elbow. See NOTE, fig. 9.
• NOTE: Long vent runs (over 12 ft.)in uninsulated air
space may require operation in CPI mode for best
performance.
